1 The World of N E W S L E T T E R smart solution for hard work

2 30 years of development, hundreds of references world wide. We call it the beginning. Versatile Watermaster replaces several singlepurpose machines. Watermaster concept: A lot has happened in three decades, since It was the year when Aquamec Ltd. introduced something entirely different to the very conventional dredging field. A completely new way to approach all shallow water work - an Amphibious Multipurpose Dredger, the first Watermaster. Watermaster became the next step in When the first Watermaster was launched the evolution of shallow water dredgers. in 1986 the world population was under While including the skills of its predeces- 5 billion.

4 The amphibious multipurpose Watermaster dredgers are widely utilised in flood prevention works around the world, including Indonesia, India, Ghana, Zambia, South Africa, Venezuela, Colombia and Russia. Watermaster operates independently without assisting vessels, separate anchors and wire-cables. The machine is self-propelled and the work attachments (such as the Cutter Pump) are connected to the flexible excavator arm, enabling cable-less working on a wide 180 degrees angle. Watermaster repositions itself quickly using its integrated stabilizers so almost the entire operational time goes to effective work. The air-cooled Caterpillar engine does not require outside water for cooling so Watermaster can operate without overheating even on dry land. The Philippines: Three Watermasters were delivered to DPWH in for the Pinatubo eruption clean-up work. DPWH soon noticed that they could utilise versatile Watermasters on a wider scale. T he Department of Public Works and Highways (DPWH) of the Philippine Government is responsible for providing and managing quality infrastructure facilities and services for the Filipino people. DPWH utilises a fleet of Watermaster dredgers to help prevent floods and to keep the shallow waterways fully operational. With over a hundred million citizens, the Philippines is one of the most populous countries in the world. It is a mountainous archipelago composed of over 7500 islands. The Country is located in a seismically and volcanically active tropical region prone to a range of natural hazards, including earthquakes, volcano eruptions, typhoons and perennial floods. In 1991 on the island of Luzon, the Mount Pinatubo volcano erupted violently, ejecting enormous amounts of ash, magma and sulfuric acid into the air. The disaster caused hundreds of causalities and massive damage to the surrounding areas. In the eruption aftermath the Watermaster concept was first introduced to DPWH. They were searching for machinery that could operate in the ash-filled shallow rivers. Watermaster s unique mobility con6 NEWSLETTER 2016 Watermaster was the missing link that complemented their existing machinery a multipurpose amphibious machine that can reach the difficult shallow water sites and carry out all work needed there. vinced the department to try a new kind of approach. The Philippines is located in the disaster prone Pacific Ring of Fire and Pacific Typhoon belt. The new complements the old DPWH had been implementing river dredging since the 1950 s. They already owned an arsenal of dredgers, but their conventional cutter suction dredgers are not amphibious and thus unable to work in the shallow waters between 0 to 2 meters depth. Their engine cooling system requires plenty of fresh water, which was a problem in the muddy waters that occur in the rainy season and made the engines overheat repeatedly. The transportation of the vessels is slow and expensive, which is why they rarely change sites. They need assembling at the site and a crane to enter and exit water. The conventional dredgers are, however, well-suited for long-lasting projects in big rivers and deep waters, where they can fully make use of their big pumping capacity. The conventional dredgers require assisting vessels, separate anchors and wire-cables in their dredging process. Their work angle is limited to roughly degrees and they need to reposition the machine and anchors often, reducing the effective work hours per day. DPWH also operates a number of longreach excavators, but these machines can only work from the shores, not from the water. Urban riverbanks are often packed with formal or informal housing, restricting excavators access to the worksites. The Philippines has suffered several serious floods in the recent past, causing hundreds of deaths and financial losses totalling billions of Euros. Millions of people have been affected by these disasters. The main reason for the flooding is that many of the inland waterways are filled with sediments and trash due to upstream erosion and the dumping of waste in the river systems, leading to a reduced water carrying capacity. The narrow, silted urban canals are especially vulnerable to flooding during heavy rainfalls of the typhoon season (from May to October). DPWH s goal is to transform the flood prone areas to flood protected areas by increasing the water carrying capacity of the waterways. They do this by dredging the accumulated silt, by removing Active waterway maintenance reduces the vulnerability to floods and secures the flow of people, goods and services, thus boosting the economy. all trash and vegetation that disturb the free flow of water and by strengthening and raising the riverbanks where necessary. The multipurpose Watermaster can handle all these operations. The depth of the Philippine waterways varies significantly between the dry and the rainy season, leaving some of them almost completely waterless during the dry season drought. The conventional dredgers could not work there yearround due to this periodic lack of water. Convinced of Watermaster s versatility, DPWH has reinforced their Watermaster fleet on several occasions between Ten new units were delivered to DPWH two years ago and were immediately put to fight floods in the Dagupan, Olangapo, Balanga, Sasmuan, Iloilo, Tacloban, Kawit, Cabagan, Paoay and Cantillan city areas. Currently DPWH has 21 Watermasters. The work continues DPWH has achieved great results with the Watermaster fleet, but the work is continuous and far from over. The Philippines location in the Pacific Ring of Fire and the Pacific typhoon belt will undoubtedly keep the need for mobile and versatile dredging high in the future, too. Dredging is a necessity required to help protect the Philippine people who live in the vulnerable low-lying areas of the country. Seasonal floods are a major problem in the Philippines. DPWH utilises 21 Watermaster dredgers in flood mitigation work. Briefly The Philippines suffers from perennial flooding The Government body DPWH uses a fleet of 21 Watermasters to help mitigate floods Results have been good and the work continues There are all together 25 Watermasters improving the Philippine waterways NEWSLETTER
